Product Highlights

The SLS-SA Level Sensor is a highly versatile and reliable instrument designed for precise level measurements in a wide range of applications. With a level range spanning from 0.5mWG to 100mWG, it offers exceptional accuracy, with options for <±0.25%, <±0.15%, and <±0.1% accuracy ratings, ensuring reliable and consistent readings.

Constructed from durable 316 stainless steel, the sensor ensures long-lasting performance even in harsh environments. Its high integrity cable gland assembly provides a proprietary sealing solution for permanent submersion, further enhancing its durability and resistance to external factors. The SLS-SA Level Sensor provides flexibility with various output configurations, including 4-20mA, 0-5V/0-10V, and 0.5 to 4.5V ratiometric, catering to different system requirements.

Moreover, its low power consumption millivolt signal enables energy-efficient operation, making it ideal for remote and battery-powered installations. Additionally, users have the option of a temperature output, adding valuable supplementary data to their level measurements. With IP68 environmental protection rated for full submersion up to 100m depth, the SLS-SA Level Sensor is a top choice for accurate and dependable level monitoring applications.

Applications

The SLS-SA Level Sensor is widely used in environmental monitoring, where it plays a crucial role in tracking water levels in natural and man-made environments. By providing accurate and reliable measurements, the sensor helps environmental agencies and researchers monitor changes in water bodies, detect trends, and respond to potential ecological threats. Its robust design ensures dependable operation even in harsh outdoor conditions, making it ideal for long-term deployment in the field.

Another important application is V-notch weir flow measurement. In this context, the SLS-SA Level Sensor is installed to measure the height of water flowing over a V-notch weir, a common structure used to determine flow rates in open channels. The sensor’s precise level readings allow for accurate calculation of flow, which is essential for water resource management, wastewater treatment, and hydrological studies.

The sensor is also extensively used in rivers, reservoirs and boreholes. In these settings, it provides continuous level data that is vital for managing water supplies, monitoring drought or flood conditions, and ensuring the safety and sustainability of water resources. Its submersible design allows it to function reliably in deep or difficult-to-access locations, such as boreholes and large reservoirs.

For industrial and commercial applications, the SLS-SA Level Sensor is suitable for tank, IBC, and tote level measurement. It can be installed in storage tanks, intermediate bulk containers (IBCs), and totes to monitor liquid levels, helping operators manage inventory, prevent overflows, and ensure process efficiency. Its compatibility with a wide range of liquids – all fluids compatible with 316 stainless steel, FKM, EPDM, or NBR seals – makes it versatile for use in various industries, including chemicals, food and beverage, and water treatment.

In the realm of telemetry and data logging, the SLS-SA Level Sensor is often integrated with remote monitoring systems. This allows for real-time data collection and transmission to central databases or control rooms, enabling operators to track water levels from afar and respond quickly to any anomalies. The sensor’s various analogue output options make it easy to interface with a variety of data loggers and telemetry equipment.

The sensor also supports flood defence monitoring and research. By providing early warning of rising water levels in rivers, floodplains, and urban drainage systems, the SLS-SA Level Sensor helps authorities implement timely flood defence measures. Its reliable performance under extreme conditions makes it a trusted tool for both emergency response and long-term flood risk assessment.

Finally, the SLS-SA Level Sensor is valuable in academic research. Researchers in hydrology, environmental science, and engineering use the sensor to gather high-quality data for experiments and field studies. Its accuracy and ease of deployment make it suitable for both short-term investigations and long-term monitoring projects, supporting a wide range of scientific inquiries.
